This harness is designed for 1992-1997 5.7L LT1/LT4 & 4.3L (V8) L99 engines with a 4L60E transmission, using a '94-'97 ECM. This harness will not work with ’92-’93 ECMs. These engines and transmissions were factory equipped in Camaro, Firebird, Corvette, Roadmaster, Impala and Caprice.

These harnesses also include a VATS bypass module, painless part #64024. The 4L60E transmission used must be a 1994+ which utilizes a 13th pin on the transmission connector. When using either of these harnesses on a '96 or '97 engine you must replace the coil, coil output wire and knock sensor with the parts from a '92 -'95 engine. Included with this harness is an 8 circuit modular fuse block and GM colour coded wires with labels for easy installation.

This standard length harness allows four feet from the back of the intake manifold to where the fuseblock and ECM mount. Perfect for those that plan to mount these components under the dash or in the glove box.

This kit includes:

All new fuel injection harness with OEM fitment connectors and harness breakouts.

OBDII connector, mounting bracket and check engine light.

Vehicle Anti Theft System (VATS) bypass module

Rubber grommet.
